m68k: sun3: Fix indentation by 5 or 7 spaces

2023-10-16T12:30:39+00:00

Indentation should use TABs, not spaces. Fix whitespace in reindented code while at it. Signed-off-by: Geert Uytterhoeven Link: https://lore.kernel.org/r/167216dfe9795056b7a69415695772887aca6d80.1696602993.git.geert@linux-m68k.org

m68k: sun3: Change led_pattern[] to unsigned char

2023-10-06T08:03:04+00:00

The values stored in led_pattern[] are only used for passing to sun3_leds(), which takes an "unsigned char". Change the type of led_pattern[] accordingly, to reduce kernel size.
